Display Container for Polyurethane Product

ABSTRACT

A display container for a polyurethane product includes a space defining a receiving section, and first edge and second edge enclosing the receiving section. The first edge provides a sealed closure. The second edge defines an opening, and the opening is adapted to be closed by the second edge after the display container is subject to a vacuumizing process to vacuumize the receiving section. When the polyurethane product is to be stored in the display container, the opening allows the polyurethane product to be inserted into the receiving section. Moreover, the polyurethane product is stored in the receiving section in a vacuumized condition.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a display container and, in particular to a display container for a polyurethane product.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

FIGS. 1 through 4 show a display container 10 for a polyurethane product 20 in accordance with a first embodiment of the present invention. The display container 10 includes a space enclosed by first edge 101 and second edge 102 thereof. The space defines a receiving section 11 the polyurethane product 20 is received therein when it is stored in the display container 10. The first edge 101 has a width defined between an inner periphery thereof that delimits the receiving section 11 partially and an outer periphery thereof that delimits a circumference of the display container 10 partially. Moreover, the receiving section 11 where the first edge 101 surrounds provides a sealed closure. Therefore, the first edge 101 can not allow the polyurethane product 20 to insert into the receiving section 11. In the preferred embodiment, the first edge 101 includes two opposing portions in a spaced relationship and a portion extending therebetween and joins the two opposing portions to form a continuous edge. Additionally, the second edge 102 defines an opening 12 thereon, and therefore, the polyurethane product 20 can be inserted into the receiving section 11 through the opening 12.

After the polyurethane product 20 is disposed in the receiving section 11, a vacuumizing device 30 is inserted from outside into the receiving section 11 through the opening 12 and is partially disposed outside the display container 10 and is partially disposed in the receiving section 11. The vacuumizing device 30 is used to vacuumize the receiving section 11 so that the polyurethane product 20 is prevented from oxidization. Additionally, the opening 12 is adapted to be reduced to a size that just enables the insertion of the vacuumizing device 30 (as shown in FIG. 2). After vacuumizing the receiving section 11, a sealing device (not shown) is used to make the second edge 102 close the opening 12 (as shown in FIG. 4). FIG. 4 also shows the sealing device creates a sealed edge 103 having a width defined between an inner periphery thereof that delimits the receiving section 11 partially and an outer periphery defined from the second edge 102 and in which the second edge 102 cooperates with the outer periphery of the first edge 11 to delimit the circumference of the display container 10. Therefore, the polyurethane product 20 is stored in a vacuumized condition and is prevented from being deteriorated due to oxidization. Preferably, the sealing device applies a thermal seal process to close the opening 12.

In addition, the polyurethane product 20 is disposed in a center of the receiving section 11 so it is equally distanced from the any portion of the first edge 101. Consequently, vacuumizing of the receiving section 11 can be accomplished successfully and easily. Furthermore, the polyurethane product 20 referred to hereinwith mainly consists of polyurethane rubber which has high-endurance, and high-durability characteristics and excellent solvent resistance. Specifically, it has 600%-800% elongation, and 2-10 times better abrasion resistance and solvent resistance than natural rubber. Additionally, the polyurethane product 20 is in a form of a strap and is flexible enough to be rolled into a coil which includes a series of concentric circles. Consequently, the polyurethane product 20 does not occupy a large space of the receiving section 11.

FIGS. 5 and 6 show a second embodiment of the present invention. The second embodiment is a display container set 100 a including a plurality of display containers 10 a detachably engaged together in a row. Each of the display containers 10 a includes a first edge 101 a having a width defined between an inner periphery thereof that delimits the receiving section 11 a partially and an outer periphery thereof that delimits a circumference of the display container partially, with the first edge 101 a providing a sealed closure, and a second edge 102 a cooperating with the outer periphery of the first edge to delimit the circumference of the display container. Also, each of the display containers 10 a is similar to the display container 10 and includes a polyurethane product 20 received therein. Each polyurethane product 20 is disposed in a center of a receiving section 11 a of the display container 10 a. The polyurethane products 20 are stored in a vacuumized condition and are prevented from being deteriorated due to oxidization. Further, a connecting edge 40 a is defined on a portion of the outer periphery of the first edge 101 a of each display container 10 a. The connecting edges 40 a of two adjacent display containers 10 a are engaged with each other, and therefore, the two display containers 10 a are attached to one another. Additionally, the two display containers 10 a are adapted to be separated form each other by disengaging from the connecting edges 40 a. In the preferred embodiment, the connecting edge 40 a for each display container 10 a is in a serrated form which includes a series of consecutive teeth.

FIGS. 7 and 8 show a third embodiment of the present invention. The third embodiment is a display container set 100 b including a plurality of display containers 10 b detachably engaged together in a column. Each of the display containers 10 b includes a first edge 101 b having a width defined between an inner periphery thereof that delimits the receiving section 11 b partially and an outer periphery thereof that delimits a circumference of the display container partially, with the first edge 101 b providing a sealed closure, and a second edge 102 b cooperating with the outer periphery of the first edge to delimit the circumference of the display container. Also, each of the display containers 10 b is similar to the display container 10 and includes a polyurethane product 20 received therein. Each polyurethane product 20 is disposed in a center of a receiving section 11 b of the display container 10 b. The polyurethane products 20 are stored in a vacuumized condition and are prevented from being deteriorated due to oxidization. Further, a connecting edge 40 b is defined on a portion of the outer periphery of the first edge 101 b of each display container 10 b. The connecting edges 40 b of two adjacent display containers 10 b are engaged with each other, and therefore, the two display containers 10 b are attached to one another. Additionally, the two display containers 10 b are adapted to be separated form each other by disengaging from the connecting edges 40 b. In the preferred embodiment, the connecting edge 40 b for each display container 10 b is in a serrated form which includes a series of consecutive teeth.

In view of the forgoing, the display container 10 is of a simple structure and it eliminates materials and eases a complicated packing process of using a conventional display container. Likewise, each display container 10 a, 10 b of the display container set 100 a, 100 b is of a simple structure. Additionally, the polyurethane products 20 are prevented from being deteriorated due to oxidization. Furthermore, the display container 10 and each display container 10 a, 10 b of the display container set 100 a, 100 b are not liable to get damaged under the thermal seal process.
